Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a conveyor apparatus for rotating a material in a material production facility,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor apparatus for material rotation in a material production facility, and more particularly to a conveyor apparatus for material rotation in a material production facility, which is a single independent facility for producing a predetermined material And a conveyor device for material rotation in a material production facility that can assist in rotating the material at a particular point in time.

Typically, automation processes for mass production are often performed continuously (e.g., inserting, inspecting, or labeling parts) while placing a workpiece on a conveyor belt and transporting it.

In the case where such a workpiece is a substrate (e.g., a printed circuit board), it usually requires a double-sided operation on the substrate. Conventionally, an operator has worked on the backside of the substrate by turning the substrate upside down on the side of the production line. The working time becomes longer and the production efficiency is lowered.

To overcome this inconvenience, a substrate reversing device has been developed for automatically reversing the substrate to continue the next operation.

However, the conventional substrate reversing device is a structure for reversing the double-sided substrate as it is positioned between two substrate production facilities for mounting parts on a substrate or performing dispensing on a processing line.

That is, after completion of the operation for mounting the components on the upper surface of the double-sided substrate by the first substrate production facility among the two substrate production facilities, the corresponding double-sided substrate is moved to the process line, Side substrate provided by the substrate reversing device being positioned is reversed by 180 占 and moved to the process line again, and the substrate reversing device is disposed on the process line through the second substrate production facility, And a component mounting operation for the lower surface.

Therefore, since the conventional substrate reversing apparatus can perform the production process for the substrate for both sides only by constructing the two substrate production facilities, the equipment cost required for the substrate production process increases, and the line length for the production process also increases The work space for producing the bar substrate needs to be secured enough to accommodate all the above-mentioned facilities. As a result, the process speed required for the substrate production process is slowed down to a certain level or less.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a material rotation system in a material production facility performs a corresponding production process performed on a material in a material production facility, which is a single independent facility for producing a predetermined material, And a process of rotating the material at the point of time.

That is, the above-described material rotation system can be implemented in a form including a rotary part, a conveyor part, and a control part in a material production facility.

Hereinafter, in order to describe the present invention in detail, the above-mentioned material will be described as an example, and the material production facility is also referred to as a substrate production facility.

1 to 6, a conveyor apparatus 100 for rotating a material in a material production facility includes a frame 110, a width adjuster 120, a lane 130, And a dispensing unit 140. [0031]

Here, the dispensing unit 140 refers to all the various process units for carrying out the substrate production process, and may be used to include a rotating unit when the rotating unit described above is mounted on the conveying unit.

That is, the dispensing unit may include a belt conveying unit, a stopper unit, a rotating unit (that is, referred to as the above-described rotating unit), a clamp unit, and a sensor unit.

The lane portion 130 in the substrate production apparatus can be constructed as a single lane or a plurality of lanes.

For example, in the case of dividing into two lanes, that is, a front lane and a rear lane, a substrate production process is performed on each lane, and the process is divided into a front lane and a corresponding dispensing unit and a rear lane and a dispensing unit desirable.

In addition, the width adjusting unit 120 is a device for adjusting the frame width between the fixed lane module and the feed lane module constituting each lane according to the size of the substrate. To this end, it is provided with a structure including a conveying guide unit, a motor, a pulley and a belt for moving the conveyance lane module to a predetermined frame width. And may further include various I / O boards, solenoid valves, sensor amplifiers, and the like.

The belt transfer unit also includes a driver, a pulley, and a belt, and serves to perform additional entry or exit of the substrate during the substrate production process.

The stopper unit stops the substrate in the working area for mounting or dispensing the substrate, or stops the substrate in the working area for rotating the substrate.

The clamp unit serves to fix or unfasten the substrate, and includes a structure in which the upper surface of the substrate is lifted up to the bottom surface of the substrate clamp cover in cooperation with the back up table.

In addition, the above-mentioned frame means a basic structure for forming the conveyor part 110, and it includes a substrate moving guide guide formation unit or a unit for guiding the moving path of the substrate, I / O boards, pressure units and so on.

The lane unit 130 can be classified into a fixed lane module and a feed lane module.

Here, the fixed lane module includes a substrate sensor for detecting the pull-in and pull-out of the substrate, a belt and motor for conveying the substrate, a substrate moving guide unit for guiding the movement of the substrate, a stopper unit for stopping the substrate at a predetermined position, And a motor for adjusting the width between the fixed lane module and the feed lane module. The substrate may be fixed in order to stably perform operations on the substrate, and the substrate may be unlocked after the completion of the operation And a clamping unit.

The conveyance lane module may include a conveyance guide unit between both lane parts, which is configured in an arrangement corresponding to the fixed lane module described above, and which allows the width adjustment between the fixed lane module and the conveyance lane module to be conveyed along a predetermined path .

Here, the rotating portion performs a function of inverting the double-sided substrate from the upper surface of the substrate to the lower surface of the substrate, or inverting from the lower surface of the substrate to the upper surface of the substrate. In some cases, the rotating part may rotate at a specific angle instead of inverting the material by 180 ° in consideration of the characteristics of the material and the working characteristics for performing the material.

In addition, since the rotary part is required to perform a rotation function in the course of performing a production process inherent to a substrate production facility such as component mounting and dispensing in a substrate production facility, It is preferable that it is provided with a structure corresponding to the internal structure.

Such a rotating part is not only mounted on a conveyor part in a substrate production facility but also easily mounted on other kinds of material production facilities and can be used as a universal mounting structure . ≪ / RTI >

As described above, the rotating portion may be additionally mounted on the conveyor portion in the already-constructed substrate production facility, or may be provided integrally with the conveyor portion, if necessary.

That is, the rotating portion may include a rotating driving pulley, a housing, and a gripper.

When the rotational driving pulley comes to a specific point in time for rotating the substrate, the power supplied from the outside may be applied to the rotation of the substrate.

The rotation drive pulley may be configured to transmit a rotational force by engaging the power provided from the outside with the belt, or alternatively may be a gear engagement structure, a CAM structure, or the like. It is also possible that the drive source is directly connected to the rotation drive pulley.

In addition, the housing of the rotary part serves to support the rotary drive pulley and the gripper, and is configured to transmit the rotational force transmitted from the rotary drive pulley to the gripper to finally support the accurate rotation of the substrate.

In addition, the housing of the rotary part may also be provided with a structure for transferring the driving force for forward and backward movement of the gripper to the gripper to finally support the forward or backward movement of the substrate.

Here, the driving force for advancing or retracting the gripper may be realized through pressure transmission through air or fluid, or may be implemented in such a manner that the gripper is advanced or retracted through the pressure transmission structure and the spring arrangement.

For example, when the driving force for advancing or retracting the gripper is realized through pressure transmission through air or fluid, as the pressure is increased on the pressure transmission path on which the driving force is provided, the guide shaft, which is located on the pressure transmission path, To implement the forward movement of the gripper and to reduce the pressure on the pressure transmission path provided with the driving force, the guide shaft located on the pressure transmission path can be pulled inward to implement the backward movement of the gripper.

As another example, when the driving force for advancing or retracting the gripper is implemented in the form of a combination of a pressure transmission structure through air or a fluid and a spring arrangement, the pressure in the pressure transmission path When the guide shaft is moved to the inside again, the pressure applied to the pressure transmission path is stopped, so that the end of the guide shaft The guide shaft can be moved to the inside of the housing by the repulsive force of the spring which is compressed in the gripper, thereby realizing the backward movement of the gripper.

In addition, the driving force for advancing or retracting the gripper can be performed through a separate driving means other than the structure using pressure and spring force as described above.

In addition, the housing of the rotary part is not only structured to transmit the driving force for advancing or retracting the gripper, but also includes a structure for providing the gripper with the pressure of air or fluid capable of performing the grip operation of the gripper .

That is, the housing of the rotary part has a first housing part for supporting the forward or backward movement of the gripper while supporting the rotation of the gripper, and a first pressure transmission path for forward or backward movement of the gripper, And a second housing portion that provides pressure to the pressure transmission path, respectively.

A bearing for supporting the rotation of the center rotary body connected to the guide shaft and the gripper pressure supply shaft is provided inside the housing of the rotary part, the gripper is moved forward or backward during the rotation of the rotary body, A rotating seal may be provided around the central rotating body.

The gripper is configured to fix the substrate in the process of rotating the substrate, and at least one gripper can be provided in the rotating portion.

As described above, the gripper can be moved forward or backward by receiving pressure from the first pressure transmission path provided in the housing of the rotary part. The gripper receives pressure from the second pressure transmission path provided in the housing of the rotation part, Operation can be performed.

As such, in addition to the manner in which the gripper moves or operates through pressure, it can also be implemented in a manner that moves or operates through a separate electrical or mechanical actuation actuator.

As the internal structure of the gripper is made of a pressure transmission type, the pressure of the air or fluid delivered from the second pressure transmission path is introduced into the internal central pipe, And the second cylinder rod is pushed out to the outside.

When the first cylinder rod and the second cylinder rod are interrupted or reduced in pressure to the inner central tube, the first cylinder rod and the second cylinder rod are displaced by the repulsive force of the spring mounted on the inner ends of the first cylinder rod and the second cylinder rod, 1 cylinder rod and the second cylinder rod can be drawn in.

It is also possible that a rake-pinion structure can be adopted to stably move the upper grip shaft and the lower grip shaft of the gripper at the same time to fix the grip to the substrate or release the grip to the substrate.

Fig. 2 is a view showing an embodiment of the substrate rotating system shown in Fig. 1, Fig. 3 is a view showing another example of the operation of the material rotating system shown in Fig. 2, Fig. 5 is a diagram showing still another example of the operation of the system.

That is, after the substrate is introduced into the substrate production apparatus, the controller performs mounting or dispensing of components on the upper surface of the substrate, and then releases the clamps for fixing the substrate to prepare for mounting or dispensing parts on the rear surface of the substrate. And performs control to move the substrate to a predetermined position as shown in Fig. 3 for rotation of the substrate.

Further, in order to rotate the substrate after the substrate is conveyed, the control unit adjusts the width between both lanes of the conveyor unit first after gripping the substrate, and then, when the width between the second lane is adjusted, And controls the rotation of the substrate by using the rotation unit.

In addition, the control unit can determine the position of the substrate to be further drawn into the substrate production apparatus based on the sensor signal provided from the substrate sensor. Accordingly, it is possible to control the process speed of the substrate when performing operations such as mounting or dispensing of the substrate in the substrate fabrication apparatus and performing rotation of the substrate.

That is, since the substrate can be pulled into the substrate production apparatus continuously while performing the production process and the substrate rotation process in the substrate production apparatus, the position of the substrate to be additionally drawn is determined at a predetermined process speed It is possible to control the speed of the rotating process of the substrate in the current operation in consideration of the occurrence of an error in the processing on the additional substrate.

In addition, the controller completes the mounting and dispensing operation on the upper surface of the substrate on the single lane in the substrate production apparatus, performs the substrate rotation using the rotation unit, and then completes the mounting and dispensing operation on the rear surface of the substrate It is possible to carry out control for drawing out the completed substrate on both sides.

The above-described control method can be performed in various ways.

For example, when there are two working areas in the substrate production apparatus, mounting and dispensing operations are performed on the upper surface of the substrate when the substrate passes through the first working area, and then, The rotation of the substrate is performed by using the rotation unit located thereon, and then, when the substrate passes through the second work area, the mounting and dispensing operation with respect to the rear surface of the substrate can be performed.

As another example, in the case where one working area exists in the substrate production apparatus, when the substrate passes through the working area, after mounting and dispensing operation is performed on the top surface of the substrate, And the substrate is moved back to the above-described work area, so that the mounting and dispensing operation can be performed again on the back surface of the substrate in the above-described working area. Thereafter, the substrate is rotated again with respect to the substrate passing through the substrate rotation region, the substrate is taken out in the substrate alignment direction at the time of being drawn into the substrate production apparatus (i.e., the substrate is placed on the upper surface) It is also possible that the rotation of the substrate is not performed again for the substrate which passes through the substrate rotation region again.

A method of rotating a substrate in a substrate production apparatus is carried out into a substrate production apparatus to make a judgment as to whether or not to rotate the substrate after completion of component mounting or dispensing with respect to an upper surface of the substrate.

As a result of the determination in the above-described step, when the substrate rotation is required, the clamp that fixes the substrate is released and the substrate is moved to the correct position for rotating the substrate.

In the above-described step, when the correct position for rotating the substrate is the reverse direction of the substrate moving direction on the rail, the substrate can be moved in the reverse direction.

Thereafter, when the substrate is placed in the correct position for rotation, the substrate is gripped by using the rotary part, and the width between the fixed rail part and the transfer rail part on the rail is fixed by a predetermined width.

Then, when a space for rotating the substrate is secured through expansion of the width between the fixed rail park and the transfer rail part, rotation is performed on the substrate by using the rotary part again.

When the above-described steps are completed, the extended width between the fixed rail park and the feed rail part is returned to the original position, and then the grip on the substrate is released through the rotary part.

Thereafter, the rotated substrate is moved to a work area for mounting or dispensing, and a clamp is set on the substrate at the time when the substrate is moved to the work area to prepare the work for the substrate.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.

The present invention also relates to a method of producing a material (e.g., a substrate), which is a single independent facility for producing a material (e.g., a substrate) Is not only sufficient but also practically usable because it can be practically carried out clearly.
